How we compare two brands

  • Only new units we can find in stock with a live price, at the same size. A brand's average says more about its size mix than about the brand.
  • A price difference counts when it is at least 5% and at least $20, and only between models that install the same way (a do-it-yourself kit is never priced against an installer-fitted system).
  • Efficiency is compared on one scale (CEER) and counts at a gap of 0.5 or more; noise counts at 3 dB(A) or more, using only ratings checked against the retailer's specification for the exact model.
  • Warranty terms are as each listing states them. Models named in a CPSC recall are never compared or sold here.

Midea vs LG: common questions

Is Midea or LG cheaper?
It depends on the size. Comparing each brand's cheapest new, in-stock model at the same size, Midea's cheapest model costs less at 12,000 BTU ($369.99 against $439), 14,000 BTU ($449.99 against $579) and 18,000 BTU ($519.99 against $699), LG's at 8,000 BTU ($249 against $309.99) and the two are within 5% or $20 at 2 sizes. These are live retailer prices and change often.
Which is more energy efficient, Midea or LG window air conditioners?
Comparing the best CEER rating each brand publishes for its in-stock models at the same size, their best ratings are within 0.5 at 2 sizes. A higher CEER means less electricity for the same cooling. Not every listing publishes a rating, so a size with a rating on one side only is not compared.
What sizes do Midea and LG window air conditioners come in?
In stock right now, Midea sells 8,000, 10,000, 12,000, 14,000, 18,000 and 24,000 BTU and LG sells 5,000, 6,000, 8,000, 10,000, 12,000, 14,000, 18,000 and 24,000 BTU. So only LG sells 5,000 and 6,000 BTU. Size the unit to the room first: an oversized unit short-cycles and leaves the air cool but damp.
Do Midea and LG make inverter window air conditioners?
Midea has 4 inverter models in stock, and LG has 4, going by each listing and the maker's model numbers. An inverter compressor slows down instead of switching on and off, which is usually quieter and more efficient at part load.
Have any Midea or LG window air conditioners been recalled?
CPSC recall 25-320 (June 2025) was issued for the risk of mold exposure; it names 3 Midea models we track (MAW08V1QWT, MAW10V1QWT and MAW12V1QWT). Those are left out of this comparison and not sold here. Check the model number on your own unit's label against the notice.
